Milton S. Hershey began making his eponymous 5¢ milk-chocolate bar in 1900, six years after he opened a factory to make chocolate to coat caramels. A second variety, with almonds, was added in 1908. The bar went global during World War II, when more than 1 billion were included in U.S. soldiers' rations.
